Today was the first day with the majority of the team back together, so the key focus today was sitting down and re-brainstorming ideas before we settle on one. As can be seen in the mind map below, the PAF idea was fleshed out and developed in more detail.
We wrote an improved proposal for both of the measurement projects about killswitches and genome integration.

Some of the team spoke to Dr Mark Ramsdale, a fungal cell biologist. He gave feedback on the PAF dea, raising the question as to why we wanted to express PAF in E. coli as opposed to a fungus. Dr Ramsdale pointed out that due to how small PAF was as a protein, using GFP as a tag could affect how it is transported around the cell, and therefore skew the results. He told us about fungi specific promoters in Neurospora crassa which acts as a Circadian Clock using light and heat as inducers.
This prompted a discussion about using a viral vector that contains a killswitch that. The viral vector will insert its genetic information in the host, a strain of Magnaportha oryzae. The Magnaportha oryzae would breed and the population would be infected with the virus containing the killswitch. The possibility of this being a heat activated killswitch was considered, so during the warmer months when plants grow the killswitch fungi is active to produce PAF.
Some of the team also met with Dr Nicky King, who is going to get us a stand at the Big Bang Science Fair for the South West (29.06.16) and the Britain Needs Scientists fair (06.07.16). She also discussed with us the possibility of writing an undergraduate Synthetic Biology module to be taken up by either Natural Sciences or Biosciences, and seemed very keen on the possibility of this.
We also met with Professor Rob Beardmore to discuss the genome integration idea. He said it sounds interesting but raised concerns about if it would even be possible to mathematically model it. He also liked the killswitch idea and said testing KillerRed and KillerOrange under a gradient of slowly increasing light intensity could be the strongest selector for resistance.

We also experimented with the vlog format, testing out the dynamics of using three people instead of two which we felt it worked a lot better.
